Notes (Only for wireless remote controller):
When using the wireless remote controller, point it towards the receiver on the indoor unit.
If the remote controller is operated within approximately 3 minutes after power is supplied to the
indoor unit, the indoor unit may beep twice as the unit is performing the initial automatic check.
The indoor unit beeps to confirm that the signal transmitted from the remote controller has
been received. Signals can be received up to approximately 7 meters in a direct line from the
indoor unit in an area 45° to the left and right of the unit. However, illumination such as fluores-
cent lights and strong light can affect the ability of the indoor unit to receive signals.
If the operation lamp near the receiver on the indoor unit is blinking, the unit needs to be in-
spected. Consult your dealer for service.
Handle the remote controller carefully! Do not drop the remote controller or subject it to strong
shocks. In addition, do not get the remote controller wet or leave it in a location with high humid-
ity.
To avoid misplacing the remote controller, install the holder included with the remote controller
on a wall and be sure to always place the remote controller in the holder after use.
If the indoor unit beeps 4 times when you are using the wireless remote controller, switch the
auto mode setting to the AUTO (single set point) mode or AUTO (dual set point) mode.
For details, refer to the included Notice (A5 sheet) or the Installation Manual.
Battery installation/replacement
1. Remove the top cover, insert two LR6AAbat-
teries, and then install the top cover.
2. Press the Reset button.

*2 The preset temperatures for cooling and heating can be set under the following conditions.
• The cooling preset temperature is greater than the heating preset temperature.
• The difference between the cooling and heating preset temperatures is equal or greater than the minimum temperature difference that varies depending on the indoor
unit model to be connected.
The settable temperature range varies with the model of outdoor units and remote controller.
Note:
Even if you press the ON/OFF button immediately after shutting down the operation is progress, the air conditioner will not start for about 3 minutes.
This is to prevent the internal components from being damaged.
3.2. Operation mode
Each pressing of the [F1] button cycles
through the following operation modes.
Select the desired operation mode.
• Operation modes that are not available
to the connected outdoor unit models will
not appear on the display.
What the blinking mode icon means
The mode icon will blink when other indoor units in the same refrigerant
system (connected to the same outdoor unit) are already operated in a
different mode. In this case, the rest of the unit in the same group can
only be operated in the same mode.

3. Operation
Automatic operation (Dual set point)
When the operation mode is set to the “ Auto ” (dual set point) mode, two
preset temperatures (one each for cooling and heating) can be set. De-
pending on the room temperature, indoor unit will automatically operate
in either the “ Cool ” or “ Heat ” mode and keep the room temperature within
the preset range.
The graph below shows the operation pattern of indoor unit operated in
the
“ Auto ” (dual set point) mode.

Room temperature is controlled to stay within the set temperature range
that is specified for the Setback mode. By leaving sufficient temperature
differentialbetweenthesettemperature for cooling (upper limit)andheating
(lowerlimit), it ispossibleto keep the roomtemperaturewithin the specified
range without overworking the air conditioners.
This setting will be especially effective during periods of non-occupancy.

•The available fan speeds depend on the models of connected indoor
units.
Notes:
●The number of available fan speeds depends on the type of unit
connected. Note also that some units do not provide an “Auto”
setting.
●In the following cases, the actual fan speed generated by the unit
will differ from the speed shown the remote controller display.
1. While the display is showing “STAND BY” or “DEFROST”.
2. When the temperature of the heat exchanger is low in the heat
mode. (e.g. immediately after heat operation starts)
3. In HEAT mode, when room temperature is higher than the
temperature setting.
4. In COOL mode, when room temperature is lower than the
temperature setting.
5. When the unit is in Drying mode.
Automatic operation (Single set point)
According to a set temperature, cooling operation starts if the room tem-
perature is too hot and heating operation starts if the room temperature
is too cold.
During automatic operation, if the room temperature changes and
remains 1.5 °C, 3 °F or more above the set temperature for 3 minutes,
the air conditioner switches to cool mode. In the same way, if the room
temperature remains 1.5 °C, 3 °F or more below the set temperature for
3 minutes, the air conditioner switches to heat mode.
Cool mode 3 minutes (switches from
heating to cooling)
Settemperature+1.5°C,+3°F
Set temperature
Set temperature -1.5 °C, -3 °F
3 minutes (switches from

Because the room temperature is automatically adjusted in order to
maintain a fixed effective temperature, cooling operation is performed a
few degrees warmer and heating operation is performed a few degrees
cooler than the set room temperature once the temperature is reached
(automatic energy-saving operation).

The airflow direction of this outlet
is controlled by the airflow direc-
tion setting of remote controller.
Fixed
The airflow direction of this outlet is fixed
in particular direction.
* When it is cold because of direct air-
flow, the airflow direction can be fixed
horizontally to avoid direct airflow.
< How to set the fixed up/down air direction (Only for
wired remote controller) >
Note:
●This function cannot be set depending on the outdoor unit to be
connected.
• For PLFY-WL·NEMU-E series, only the particular outlet can be fixed
to certain direction with the procedures below. Once fixed, only the
set outlet is fixed every time air conditioner is turned on. (Other outlets
follow UP/DOWN air direction setting of remote controller.)
■Explanation of word
• “Refrigerant address No.” and “Unit No.” are the numbers given to
each air conditioner.
• “Outlet No.” is the number given to each outlet of air conditioner.
(Refer to the illustration below.)
• “Up/Down air direction” is the direction (angle) to fix.

Notes:
Any person at the following places cannot be detected.
●Along the wall on which the air conditioner is installed
●Directly under the air conditioner
●Where any obstacle, such as furniture, is between the person and
the air conditioner
A person may not be detected in the following situations.
●Room temperature is high.
●A person wears heavy clothes and his/her skin is not exposed.
●A heating element of which temperature changes significantly is
present.
●Some heat sources, such as a small child or pet, may not be sensed.
●A heat source does not move for a long time.
The 3D i-see Sensor operates once approximately every 3 minutes
to measure the floor temperature and detect persons in the room.
●The intermittent operating sound is a normal sound produced when
the 3D i-see Sensor is moving.
Notes:
●During swing operation, the directional indication on the screen
does not change in sync with the directional vanes on the unit.
●Available directions depend on the type of unit connected.
●In the following cases, the actual air direction will differ from the
direction indicated on the remote controller display.
1. While the display is in “STAND BY” or “DEFROST” states.
2. Immediately after starting heat mode (while the system is wait-
ing for the mode change to take effect).
3. In heat mode, when room temperature is higher than the tem-
perature setting.

AUTO (dual set point) mode:
In AUTO (dual set point) mode, the preset temperatures can be set for cooling and heating, and operation can be switched automatically between
cooling and heating depending on the room temperature.
The preset temperatures for cooling and heating set in AUTO (dual set point) mode will be reflected to the temperature setting for COOL/DRYING
and HEAT modes.
SETBACK mode:
The SETBACK function automatically switches the operation mode between cooling and heating to maintain the room temperature within the set
temperature range.
The preset temperatures for cooling and heating set in SETBACK mode can be different from the preset temperatures for other modes.
